Smoldering burning is the final phase of a fire where visible flames are no longer present, but extreme heat persists. This occurs when the available fuel is nearly consumed, or oxygen is limited, creating a high- temperature environment without active flames. It poses a serious re-ignition risk.
Ignition stage (B) is the beginning of the fire.
Last stage (C) is too vague.
Incipient stage (D) refers to the early development before flames appear.

Project specifications define system requirements, including performance expectations such as detection accuracy, response times, image quality, or access control capabilities. These expectations guide vendors in delivering compliant solutions and help measure system acceptance upon completion.
A (Cost) is part of project budgeting, not specifications.
B and C (Testing and tolerances) may be included but are not the core element.

Fidelity bonds specifically cover losses resulting from dishonest acts committed by employees, such as theft, fraud, or embezzlement. These are commonly used in financial institutions and other sectors where employees handle cash or sensitive assets.

Standoff distance refers to the space maintained between a potential explosive threat (such as a vehicle-borne improvised explosive device, or VBIED) and the target asset. Increasing standoff distance significantly reduces the impact of a blast by leveraging the inverse-square law, which governs blast pressure dissipation over distance.
A (Blast radius) is the area affected by an explosion.
B (Impact area) refers to where a blast or projectile strikes.
C (Clear zone) is used in security but does not specifically refer to bomb offset.

Post-implementation evaluation testing should be performed at least annually to assess whether the security system continues to meet operational requirements. It also ensures that performance standards are upheld, and helps identify any necessary updates or improvements.
A, B, and C are more frequent than typical industry best practice unless special conditions apply.
